Watch The Weeknd bring out Drake in London.

On top of giving the crowd a surprise performance, Drake sung praise for Abel, who worked with him on 2011's Take Care after Drake discovered him while he was working on his debut project House Of Balloons. "You played me 'What You Need.' After that, we met up at the studio and I heard House Of Balloons, which is in my top 5 albums of all time," Drake recalled of his early meeting with Abel.

He closed his speech with the declaration: "OVO and XO forever, it doesn't matter where we are."
